In infants vaccinated against measles and Diphteria/Tetanus/Pertussis (DTP), a (relatively weak) negative association between the number of CD127Lo FoxP3+ Tregs present in the periphery and the antibody response to measles vaccination, but not DTP vaccination (Diph-Tet-Pert) was shown (86). The gene discussed is FOXP3; the disease is measles.
